A shopkeeper buys an article for Rs. 450. He marks it at 20% above the cost price. Find the percentage discount given by him if he sells the article for Rs. 496.80.
C.P. = 450
He marked it by 20% => $$\frac{20}{100}$$ * 450 = 90
Marked price = 450+90 = 540
S.P. = 496.80
Discount % = $$\frac{540-496.80}{540}$$ * 100
= $$\frac{43.2}{540}$$ * 100 = 8%
